| titleOfInvention | Manufacturing method of permanent magnet gear |
| abstract | The present invention relates to a method of manufacturing a permanent magnet gear, and more particularly, to the magnetic properties of the anisotropic injection magnet in more detail by having an oxide-based injection layer, a permanent magnet gear magnet layer and an external injection layer having a plurality of laminated structure and composite structure To increase the rotational torque and to improve the oxidation resistance of the inner diameter part of the permanent magnet gear, and to inject the inner and outer diameter parts of the permanent magnet gear with epoxy resin to protect the permanent magnet gear from the oxidizing atmosphere, By performing anisotropic magnetic field injection with an oxide-based ferrite so that the magnetic properties are maximized by injection, the method of manufacturing a permanent magnet gear providing a magnetic gear with improved oxidation resistance while improving the magnetic flux density at the magnet surface of the permanent magnet gear. It is about.n n n The present invention comprises the steps of preparing an injection anisotropic magnet by injecting a mixture of the oxide-based ferrite powder and the thermoplastic resin in a radial anisotropic or polar anisotropy using an injection magnetic molding technique; Inserting the injected anisotropic magnet into the inner side of the permanent magnet gear assembly; Inserting the injection anisotropic magnet inserted into the permanent magnet gear into a mold having an outer diameter greater than that of the permanent magnet gear to injection molding the thermoplastic resin into the inner and outer diameters of the permanent magnet gear; Making the oxide-based injection layer, the permanent magnet gear magnet layer, and the external injection layer have a plurality of stacked structures and complex structures; Manufacturing the thermoplastic resin to protect the inner and outer neck portions of the permanent magnet gear from the outside; Characterized by including.n n n Therefore, the present invention improves the magnetic resistance of the anisotropic injection magnet to increase the rotational torque and at the same time to improve the oxidation resistance of the inner diameter of the permanent magnet gear, and to improve the magnetic flux density at the magnet surface of the permanent magnet gear at the same time. The magnetic properties can be controlled by changing the thickness and characteristics of the oxide-based ferrite layer in the inner diameter to suit the performance and characteristics of the permanent magnet gears, and the surface scratches that may occur during the assembly of the permanent magnet gears. Can be protected from breakage, thereby improving the manufacturing efficiency of the permanent magnet gear has the effect of maximizing manufacturing productivity and satisfaction.n n n n Oxide-based ferrite powder, thermoplastic resin, permanent magnet, permanent magnet gear, surface magnetic flux density, oxidation resistance, magnetic properties improvement, internal and external diameter protection, economical efficiency. |
